Before the school year begins, the anti-social Selinee Karasuma meets a few girls in an ice cream parlor, and as if by magic, they become great friends. However when all of them suddenly experience unexplainable events, Selinee realizes she did not meet these girls by accident. It is revealed that Selinee is in fact a descendant to the power of the Red Fox given by her grandmother in a spiritual world. She tells Selinee that she needs to protect the earth from aliens that seek revenge on mankind. The girls she met at the parlor are in fact her "soul sisters" or in other words partners that will help her defeat their enemies. Throughout this, Selinee is still dealing with the daily difficulties of life.
